Hi i am doing a report for my 6 grade science class. I was wondering if you could answer the following question?

Do you think you know everything about the sun?

There are still many unanswered questions about the Sun which astronomers are trying to find out about. These include how come the corona is so much hotter than the visible surface of the sun, how sunspots form and why their numbers vary on an 11 year cycle, among other things.
